DIN-rail fuse holder for three phases and neutral using 10 × 38 mm fuse cartridges.

## In plain English

### What it does

A fuse holder supports a replaceable fuse and connects it into the circuit. The fuse is the part designed to open under specified excessive-current conditions.

### A simple example

In a switchgear control panel, a holder gives a fuse a defined mounting and connection point in the control supply.

### What the drawings help you do

Use the selected manufacturer's drawings to check the equipment's size, mounting points and cable connections. The layout helps you plan where it fits and how it can be reached for maintenance. An illustrative 3D preview does not establish product dimensions or required clearances.

### Terms

- Current: The flow of electrical charge, measured in amps.
- Rating: A value stating the conditions for which equipment is specified.
- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

Reserve the holder body and the opening space needed to access the cartridges. Its four-module assembly belongs on the rail layout; fuse ratings belong in the circuit schedule.
Use the linked manufacturer CAD for dimensions and the exact selected configuration. The downloadable illustration here is original educational geometry, unitless and not to scale.

## How to read it

- The manufacturer identifies this version without a status indicator. Keep the neutral position and phase order consistent with the wiring diagram.
- The holder rating is not the rating or operating characteristic of the fuse installed in it.

## Information to show or reference

- Check the 3P+N pole arrangement.
- Reserve cartridge-carrier opening and terminal access.
- Specify fuse type and rating separately.

## Important distinction

The holder rating is not the rating or operating characteristic of the fuse installed in it.
